问题 Ok, I've been going at this for several hours and I simply cannot find the solution. I want to get some data from my user. So first, I use a controller to create a view which receives a Model: public ViewResult CreateArticle() { Article newArticle = new Article(); ImagesUploadModel dataFromUser = new ImagesUploadModel(newArticle); return View(dataFromUser); } Then, I have the view: <asp:Content ID="Content1" ContentPlaceHolderID="MainContentPlaceHolder" runat="server"> <h2>AddArticle</h2> <%

Getting the original files create date upon upload

由 六月ゝ 毕业季﹏ 提交于 2019-12-08 07:56:52
问题 We have a process in place that uploads files to our website. It has become important to the users to be able to see when those files were created. I'm looking for a way to extract the original create date from the HttpPostedFile. If anyone has an idea for me I'd really appreciate it (I'm a bit stumped at this point). 回答1: You don't have access to the date the file was created on the client. You can use Fiddler to validate this. I believe the only data you'll see being posted is the filename

问题 I have an HttpPostedFile object and just need to extract the content of the posted file. I found this link but that's a very long process to just obtain a string with the content. Is there any shorter way?

C# - I cannot reference HttpPostedFileBase

由 佐手、 提交于 2019-11-30 08:13:09
问题 I am using MVC .NET in a distributed environment with CSLA and I can reference HttpPostedFileBase from one of my web layers (eg Website.MVC), but I cannot reference HttpPostedFileBase from a separate layer (lets call it OtherLayer.Web). Any idea on what I need to do to be able to call HttpPostedFileBase ? I am able to use HttpPostedFile in both layers - should I just use this instead? The assembly references are basically the same - in Website.MVC I have: namespace Website.Mvc.Controllers {

HttpPostedFile.FileName - Different from IE

由 ∥☆過路亽．° 提交于 2019-11-28 07:21:08
When I upload a file to a site using the ASP:File control the FileName property is different in IE and Firefox. In Firefox, it just provides the name of the file, but IE provides the full path to the file. I have worked around this by adding the code: Dim FileName As String = file.FileName If FileName.LastIndexOf("\") > 0 Then FileName = FileName.Substring(FileName.LastIndexOf("\") + 1) End If But I'm not sure why that would be different between the different browsers. Does anyone know the reason for this? Thanks. This is a security/privacy concern, firefox/mozilla is doing it right and you
